Just happened tonight. Any thoughts will be appreciated.

V1 (MP2). shorty ($73)
V2 (MP3). Loose white male ($400). VPIP 80%ish from 1 hour of observation.
Hero (BB). Covers.

Folds to V1 who makes it $15. V2 calls. SB calls. Hero calls with Ac4c.

Flop ($60-rake) AhQc7c

Hero checks. V1 bets $20. V2 calls. Hero raises to $75. V1 calls all in. V2 calls saying, "How many aces are in the deck?"

Turn ($268-rake) 9d

Hero's action?

What are the pros and cons of betting 1/2 pot, pot, or shoving?

Thanks again.

This spot is exactly why I dont check raise the flop with hands like this. If he got this far, hes probably not folding a good ace and you are in no mans land now.

I prefer to bet and if I get raised I can shove.....or just check/call and look for the flush or 2 pair.

Sure he's vpip is through the roof. But how has he been playing post flop?
Calling a lot? Getting overly committed with top pair?

Does he seem to have a fold button?
If he has a fold button I'd bet $225 on the turn. If he doesn't, I'd check and see what he does. It's important to note that we still have sdv against V2. He can certainly have some worse flush draws in his range as he was getting a good price to call after V1 called. And he likely doesn't have that many sets in his range after flatting twice on the flop. So it's mostly just AQ and A7 we have to worry about. That and a bunch of KXcc/T9xx, 98cc, T8xx type hands.

With a weak sizing I'm going to ck/jam, with a mid to strong sizing I'll prolly check/call.
